To 'all who/m rif; 'may concern: l y Be it known thatre, Jenn it. Zinsen and yescrow Z'srsnn citizens of the United States, 'residing-ot Berwick, in the county of Coburn bis and State of Pennsylvarnn, have invented certain new and useful improvements in Forms for Concrete Sidewalks, of which the follow-'ing is aspeciioation. Y

In constmoting side walks of concrete it is lpeecston of Eletters Patent.

generally necessary to set up confining strips,

which are usually held in pisco by regs driven into the earth and in order to low for contraction and expansion, the 'walk 1s 1 inward displacement. A notch 4 '1s formed ,l suhdivlded into blocks, either-by cuts or by I lremoved ond easil interposingstnps of felt or the like.

The present invention has for its object to facilitate 'and cheapen the construction oi concrete side walks and to save material.

In accordance with this'invention, rails or strips are arranged along opposite edges .of the line oi' pl'escrihed'rifalk, and "said strips to separate the Welk into sections, the parte bei of suoli oonstruotion as to admit of the tie'p ates and comining strips being rcodily y and quickly pissed in ppsition es the Work pro esses. f

f :For e full nnderstendingn ofthe. invention and the merits thereof van also to'scquire s vknowledge of the details of construction ind the means for etecting the result, reference 1s to be had tothe following description and. accom anylng drawings.

l' 'le the inventxen'nmy be adapted to different forms and conditions by ohanges'in l the structure and minor'details without deperti from the spirit or essential features there@ stili the preferred .embodiment is shown in the accompanying drawings, in

which:

Corresponding end like per eure referred to in the following description and indicated in all the views of the drw'rnngs by the seme reference cherscters i accordance with tins invention, citer the hedlo the 'walk hos been prepared in the 1 'usual manner, confining strips i nre placed along the sides thereof and ere omed ily tre plates 2, the latter being s ace epsrt distance corresponding te t e lengte or the l l l Patented.

blocks 'or sections. The strips' 1 may be of. any length, width and thickness and arelusually wooden rails a proximately two 'by' four inches and of any ength.

The tie Iplates' 2 are of metal'and are approximate y one-fourth of an inch thick and approximately six inches wide and may be of o ength corresponding to the width of the Walk. The tie plates are formed in each'end with openings 3 to receive the conning strips over whioh'they are fitted, thereby preventing lateral movement of said strips and holding them both against outward or in the outer vertical edge of the plate bordering u on theo 3 and isde ed to receive wedge. oil-)klelylg by means sdlivhich the tie plates and confining strips are held in place. Byhavin the notches 4 formed in the outer edges/o the portions of the plates bordering upon the openings 3, the wedges or keys 5 are located wholl exterior to the y stripsand may e readily tightcned or oosened. j'llhe tie plates 2 1n addition to retalnmg t e coninm' g stri s 1 in lace also' serve to subdivide't Wzilk into blocks or sections, whereby provision is had for contractionl and expansion without a1- lowing the walk to crack or break irregularly, which would be the case'if no provision .were had for contraction and @lz-pensionA by separating the continuous wa into blocks or sections.

The co s trips 1 and the tie plates 2 constitutel in e ct a form for receiving the concrete or like material employed in the formation of the walk, said material after being mixed in the 'usual w and filled into the s ace between thefco stri s and. tie ates, being tamped ushed an trowele in Y the accustomedway; After the walk has set suciently to admit of the con- 1 ning strips and tie 'plates being removed ,I

with safety, the Wedges or-keys 5 are driven from the notches land the tle plates lifted, after which the confining easily se arated from the walk, the spaces 'formed y the tie plates be' fmishedn any desired way. Itwill be uxrlierstood that there'is no necessity or occasion f the confining strips' to the ground y the nsual pegs-.hence the. said strips may be strips may be" easily removed without disturbing the/walk and used repeatedly.

in the modiicatlon shownrin Fin'fi, the tie plate 2 is reduced in width, inte ediate of its end portions to admit orts u per edge coming in the plane of the top e ge of the i ed e of the plate.

confining strips so that in constructing a sidewalk, the surplus material may be moved from' one section to the nextadjoining section by brushing the same over the upper Walks of concrete or like material, the same p comprising spaced conning strips, tie plates having slots near their ends extended transvers'el thereof in an upward direction from.

their ower edges to receive said connin strips by slipping over their up -er edges, an' having transverse notches in t e outervertical ed es of the 'said-slots, and keys adapted to be riveli into said notches after securing 'thentiejplatepand confining strips.

2. A ergnlfor use in vconstructing side Walks of concrete '6r like material, the same comprising 'spaced-coniiliin strips and tie lower edges of the said tie' lates and adapted' toslip over the conning s ips, the outer v ertical edges of said slots having transverse notches, and keys ada ted to be driveninto said notches to secure t e tie plates and confining strips.
